    I. Core Pharmacological Effects
    1. Enhancing the maturation and differentiation of T lymphocytes
    - Acting on the bone marrow and thymus
    - Increasing the quantity and activity of helper T cells (CD4) and cytotoxic T cells (CD8);
    2. Enhance cellular immunity and antiviral immunity
    - Stimulate T cells to secrete antiviral cytokines such as interferon (IFN-α/γ), interleukin IL-2, and IL-12;
    - Strengthen the ability of NK cells (natural killer cells) to kill infected and mutated cells;
    - Improve the antigen-presenting ability of dendritic cells to better recognize viral and tumor antigens.
    3. Regulate humoral immunity
    Support the differentiation of B cells, moderately promote the production of specific antibodies, and improve the low antibody response.
    4. Inhibit excessive inflammation and alleviate immune damage
    Downregulate excessive pro-inflammatory factors, reduce inflammatory storms; have protective effects on inflammatory damage caused by autoimmune disorders and severe infections.
    5. Anti-tumor Synergistic Effect
    - Enhances the ability of immune cells to recognize and kill tumor cells;
    - Reduces the immunosuppression caused by radiotherapy and chemotherapy;
    - Can be combined with immune checkpoint inhibitors to enhance the anti-tumor efficacy.
    II. Clinical Indications
    1. Chronic Viral Hepatitis
    Auxiliary treatment for chronic hepatitis B and C: Enhance antiviral immunity, help control the virus, and improve liver function.
    2. Severe Viral Infections/Recurrent Infections
    - Recurrent respiratory infections, chronic bronchitis, pneumonia;
    - Severe viral infections (influenza, severe COVID-19, herpes virus, etc.);
    - Prevention of infections in immunocompromised individuals.
    3. Cancer Radiotherapy and Chemotherapy Assistance
    Used during radiotherapy and chemotherapy for lung cancer, liver cancer, gastrointestinal tumors, etc.: Reduce bone marrow suppression, restore immunity, and lower the risk of infection.
    4. Immunodeficient Individuals
    Congenital/secondary immunodeficiency (elderly, long-term hormone use, diabetes, post-operative weakness, long-term bedridden).
    5. Vaccine Enhancement
    For immunocompromised individuals (elderly, dialysis patients, cancer patients): Use in combination with flu, pneumonia, and hepatitis B vaccines to enhance vaccine antibody response and improve protection efficacy.
    III. Other Benefits
    1. Anti-aging: Improves immune decline (immunosenescence) in the elderly population;
    2. Post-operative recovery: Facilitates rapid immune recovery after surgery, reducing incision and pulmonary infections;
